Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter door which can be long in the use state and short in the stored state, and is particularly applied to a horizontal pull shutter door. The present invention relates to a shutter door having a structure suitable for.

[0002]

2. Description of the Related Art Shutter doors have come to the present with almost no structural changes since the time when they were called shutters, but they are engaged with the long sides of metal or synthetic resin slats. It is common to construct a shutter door of the required length by providing an engaged portion and an engaged portion, engaging the engaging portion of the slat with the engaged portion of the adjacent slat, and repeating the engagement one after another. It was a simple method.

The shutter door thus constructed can be bent to a certain angle at an engaging portion with an adjacent slat, and by utilizing it, it can be wound into a storage portion (for example, a door pocket) or an appropriate guide means. It is used to change the direction of movement of the shutter door.

[0004]

Generally, the shutter door is stored in a form of retracting into a door pocket or of being stored in a storage part. In particular, in the case of a form of storing in a storage part. The diameter of the shutter door when wound up depends on the width of the slat and the allowable angle of bending around the engaging portion.

By reducing the width of the slat alone, the diameter at the time of winding and housing can be reduced, but
By doing so, the number of slats for constructing a shutter door of a certain length increases, and the number of engaging parts also increases.Therefore, the number of parts increases, which increases the number of steps during construction, the weight of the shutter door, etc. In addition to the above problem, it is not possible to reduce the diameter of the reel when it is accommodated in the reel.

Further, the engaging portions of the slats are adjusted,
Although it is possible to increase the bending angle in that portion, increasing such an angle for mischief causes a decrease in the strength of the shutter door and also leads to deterioration of the shutter door installation, which is a desirable result. You can't get it.

[0007]

[Means for Solving the Problems] In recent years, a technique for drawing and molding using aluminum or a synthetic resin as a material has been developed, and an arbitrary molding material can be obtained. Therefore, a slat using the method is manufactured. However, the applicant of the present application has arrived at a new solution in view of the present situation.

The applicant of the present application has found that the limit of the storage size of the shutter door at the time of storage is due to the fact that the shapes of the slats used for one shutter door are all the same. , I realized that if one of the adjacent slats can be accommodated in the other, the size of the shutter door can be reduced by about 50% in the longitudinal direction.

To this end, two types of slat structures used for the shutter door are prepared, the first slat serves as the accommodating plate, the second slat serves as the sliding plate, and the accommodating plate has a connecting portion or a sliding plate. It is suitable to install a connected part and to house the sliding plate in the housing plate. It is desirable that the sliding plate is slidable within a certain range, but is housed inside the housing plate in a state where it does not fall off from the housing plate.

A large number of a set of slats comprising the accommodation plate and the sliding plate configured as described above are prepared, and the connecting portion of the accommodation plate of one set is engaged with the connected portion of the sliding plate of another adjacent set. Let
A shutter door having a required length can be obtained by sequentially repeating the steps.

When the shutter door thus constructed is used (for example, when the opening is closed), all the sliding plates are used by being pulled out from the accommodating plate and accommodated in the accommodating part such as a door pocket. In this case, since the sliding plate is stored deeply inside the storage plate, the total length of the shutter door may change depending on the usage condition and the storage condition, and the shutter door may be stored in the storage part with a shorter total length. It will be possible.

[0012]

[First Embodiment] A first embodiment will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a set of slats used in a shutter door according to the present invention, showing the shutter door housed in a housing, and FIG. 2 shows the slats shown in FIG. It is a cross-sectional view of the state of being.

In FIGS. 1 and 2, reference numeral 1 is a receiving plate having a connecting portion 2, and 3 is a sliding plate having a connected portion 4. In this embodiment, the sliding plate 3 has cylindrical portions 3'and 3'extended in the longitudinal direction at both ends thereof.
Are connected by a base 3 ″ having a thickness smaller than the diameter of the cylindrical portion 3 ′. One cylindrical portion 3 ′ is inside the accommodation plate 1 and the other cylindrical portion 3 ′ is the accommodation plate. 1
The base 3 ″ that is external to and connects them penetrates the opening 1 ′ of the receiving plate 1 and can freely slide in and out of the receiving plate 1 within the range permitted by the opening 1 ′.

On the opposite side of the opening 1'of the receiving plate 1, a connecting portion 2 which is continuously recessed along the longitudinal direction of the receiving plate 1 is installed, and is located outside the receiving plate 1 of the sliding plate 3. A connected portion 4 that should cooperate with the connecting portion 2 is provided on the cylindrical portion 3'in a protruding manner. The sliding plate 3 is inserted from the longitudinal direction of the accommodating plate 1, and a state in which the sliding plate 3 is completely inserted is shown in FIGS. 1 and 2.

The connected portion 4 of the sliding plate 3 of one set of the slats thus constructed is inserted into the connecting portion 2 of the accommodating plate 1 of the other set from the longitudinal direction of the slats to connect them. By repeating the connecting operation, a shutter door having an arbitrary length can be formed.

In using the shutter door, when the slat is pulled out manually or by a separately prepared driving means, the shutter door can be used in a state where the sliding plate 3 is maximally protruded from the accommodating plate 1. When this is stored in a storage part such as a door pocket, it can be stored with the sliding plate 3 being pushed into the storage plate 1 with the shutter door having the shortest overall length.

In this first embodiment, the total length of the set of slats shown in FIG. 1 at the time of accommodation is about 100 mm, and FIG.
The total length in use shown in is designed to be 155 mm. Therefore, the total length of the shutter door when stored can be shortened to about two-thirds of the time when it is used. Further, since the planar angle change between the connecting portion 2 and the connected portion 4 in the drawing can be about 30 degrees to the left and right with respect to the moving direction of the shutter door, a radius of a little less than 170 mm when stored. It can move along an arc, and when used, it can move along an arc with a radius of less than 280 mm.

[0018]

Second Embodiment A second embodiment is shown in FIGS. The structure shown in this embodiment has substantially the same structure as that of the first embodiment, but the sliding plate 3a has a slip-off protrusion 3a 'inside the housing plate 1a and projects from the housing plate 1a. All the parts that have been formed have the same thickness, and the connected portion 4a is provided at the tip thereof.
Is different from the structure of the first embodiment.

In the second embodiment, the accommodating plate 1a is the sliding plate 3
It is exactly the same as that of the first embodiment in that it has a connecting portion 2a that accommodates a and that accommodates the connected portion 4a of the sliding plate 3a of the adjacent pair of slats.

In this embodiment, the total length of the set of slats in the storage state shown in FIG. 3 is about 43 mm, and the total length in the use state is about 73 mm. It can be shortened by 40% or more.
The planar angle change in the figure between the connecting portion 2a and the connected portion 4a can be about 30 degrees to the left and right with respect to the moving direction of the shutter door, so that the radius of 70 degrees when stored.
It can move along an arc of less than mm and has a radius of 120 when used.
It can move along an arc of a little less than mm.

Although the above two embodiments have been described with respect to the horizontal pull shutter door, the present invention can be applied to the conventional vertical pull shutter door by appropriately designing the housed state and the driven state. Further, by appropriately designing the size and shape of the accommodating plate and the sliding plate, it is possible to obtain an arbitrary shutter door suitable for any usage condition.

[0022]

As described above, according to the present invention, there is an effect that the total length of the horizontal pulling shutter door when stored can be greatly shortened, and at the same time, the storage radius by winding when storing can be made extremely small. This has the effect of widening the range of applications for the horizontal pull shutter door.
